Pancreatic cancer often presents at an advanced stage that result in a very dismal five-year survival rates. Novel methods to detect tumors as early as possible are desperately needed. The U.S. Preventive Services Task Force (USPSTF) recommends against routine screening for pancreatic cancer in asymptomatic adults using abdominal palpation, ultrasonography, or serologic markers. The evidence for diet-based prevention of pancreatic cancer is limited and conflicting. Recommendations about lifestyle changes, such as stopping the use of tobacco products, moderating alcohol intake, and eating a balanced diet with sufficient fruit and vegetables is generally made. However, screening for persons with hereditary predisposition to develop pancreatic cancer has not been included in this review. Biomarkers represent one tool for the early detection of small, surgically resectable cancers in both the general and high risk populations. Some of the currently utilized biomarkers including carcinoembryonic antigen (CEA), CA 19-9, SPan-1, and DUPAN-2 unfortunately have yet to show the sensitivity and specificity needed to be used for screening asymptomatic patients in the general population for pancreatic cancer. Herein, the authors report some updated information from the 2010 ASCO Gastrointestinal Cancers Symposium in detecting early stage pancreatic cancer.
胰腺癌通常在晚期才出现,导致五年生存率非常低。迫切需要尽早检测肿瘤的新方法。美国预防服务工作组(USPSTF)建议,对于无症状成年人,不建议使用腹部触诊、超声检查或血清学标志物对胰腺癌进行常规筛查。基于饮食预防胰腺癌的证据有限且相互矛盾。通常会给出关于生活方式改变的建议,比如停止使用烟草制品、适度饮酒以及食用富含足够水果和蔬菜的均衡饮食。然而,本综述未涵盖对有胰腺癌遗传易感性人群的筛查。生物标志物是在普通人群和高危人群中早期检测可手术切除的小癌症的一种工具。不幸的是,目前使用的一些生物标志物,包括癌胚抗原(CEA)、CA 19 - 9、SPan - 1和DUPAN - 2,尚未显示出用于筛查普通人群中无症状胰腺癌患者所需的敏感性和特异性。在此,作者报告了2010年美国临床肿瘤学会(ASCO)胃肠道癌症研讨会上关于检测早期胰腺癌的一些最新信息。
